BACKGROUND: The history and physical examination will usually direct a surgeon to the correct site of joint pathology. Imaging with plain radiographs and diagnostic injections help localize joint pathology more precisely. The presence of accessory communications between adjacent joints may reduce the sensitivity of these investigations. MATERIAL AND METHODS: We report on the findings of 389 arthrograms of the midfoot, hindfoot and ankle that were performed by a single radiologist over a 7-year period. Fluoroscopic guidance with radioopaque dye was used to confirm needle position before local anesthetic was injected. Images were closely studied to identify any communication between adjacent joints. RESULTS: The passage of contrast into adjacent joints confirmed the presence of an additional communication. In 13.9% of cases there was a communication between the ankle and subtalar joint. A communication between the talonavicular and the calcaneocuboid joint was observed in 42.3% of local injections. We identified previously unreported communications between the anterior subtalar and the naviculocunieform joints (8%), the anterior subtalar and the calcaneocuboid joints (9%) and the naviculocunieform and tarsometatarsal joints (1.1%). CONCLUSION: This study reinforces the typical incidence of known joint communications, describes previously unreported communications and highlights the importance of these communications particularly with the small joints of the midfoot. The possible presence of accessory communications must always be considered when performing isolated midfoot fusions relying upon diagnostic local anesthetic injections. [ABSTRACT FROM AUTHOR]

Background. We report a patient with ossification of the Achilles tendon, presenting plain radiographs, ultrasound, power doppler, computed tomography and magnetic resonance findings. The majority of the tendon was ossified, and there was adjacent soft tissue oedema. The appearance of peritendinous oedema associated with ossification has not, to our knowledge, been reported in the literature, and could account for hindfoot pain in cases of tendon ossification. Method. A review of 44 articles on aetiology, histology and imaging was performed. Results. Trauma, either accidental or from surgery, rather than tendinopathy is the likely aetiological factor. Conclusion. The Achilles tendon usually responds to an insult with the development of mature bone, not dystrophic calcification, with no evidence of inflammatory or degenerative changes.

Introduction:The approach to the distal radius to apply a volar buttress plate for a volarly displaced distal radius fracture is a familiar procedure for orthopaedic surgeons. The stabilisation of distal tibia posterior malleolar fractures is commonly performed by inserting lag or cannulated screws into the posterior fragment from anteriorly.Method:We discuss the similarity of the application of a posterior buttress plate to the distal tibia via a posterolateral approach compared with a distal radial approach.Conclusions:The posterolateral approach is easy, safe and allows good access and accurate direct fracture reduction. We recommend this method be considered for the stabilisation of a posterior malleolar fracture. [ABSTRACT FROM AUTHOR]

Sequential fatigue fractures of the fourth, second, and third metatarsals in the same foot are reported for a military aviator in the absence of abnormal stresses or underlying bone disease. The likely etiological factor is altered foot biomechanics, as identified in pedobarographic assessment. We have reviewed the literature regarding multiple metatarsal stress fractures.

Purpose: The aim of this study was to investigate how fear of reinjury to the Achilles tendon affects return to previous levels of physical activity and self-reported Achilles tendon Total Rupture Score (ATRS) outcomes., Methods: Data were collected from a large cohort of patients treated for an acute Achilles tendon rupture at Sahlgrenska University Hospital Mölndal between 2015 and 2020. The ATRS and additional questions concerning fear of reinjury, treatment modality, satisfaction of treatment and recovery were analyzed 1-6 years postinjury. Analysis was performed to determine the impact of fear of reinjury on patient-reported recovery and physical activity., Results: Of a total of 856 eligible patients, 550 (64%) answered the self-reported questionnaire and participated in the follow-up. Of the participants, 425 (77%) were men and 125 (23%) were women. ATRS, recovery in percentage, satisfaction of treatment, recovery on a 5-point scale and physical activity level post- versus preinjury were significantly related to fear of reinjury ( p  < 0.001). Of the nonsurgically treated patients, 59% reported fear of reinjury compared to 48% of the surgically treated patients ( p  = 0.024) Patients that reported fear of reinjury had a 15-point lower median ATRS score than those who did not ( p  < 0.001)., Conclusion: More than half of patients who have suffered an Achilles tendon rupture are afraid of reinjuring their tendon. Patients who reported fear of reinjury exhibited a significantly lower ATRS score. This indicates the importance of addressing psychological aspects in the treatment after this injury., Level of Evidence: Level II., Competing Interests: The authors declare no conflict of interest., (© 2024 The Author(s).

Purpose: Achilles tendon ruptures (ATRs) close to the insertion, in high-level athletes, and in patients at high risk of re-rupture, may be better suited to operative repair. Minimally Invasive Repair (MIR) of the Achilles tendon has excellent outcome and low complication rates. Traditionally MIR has showed lower repair strength, failing due to suture pull-out from the distal tendon stump. The aim of this study was to describe the outcome of ATR patients who received transosseous distal suture placement using a standard technique as a reference., Methods: Following ATR, patients were evaluated for pre-injury activity level, body weight, location of the tear and size of the distal Achilles tendon stump. Patients considered to be at high-risk of re-rupture: Tegner level ≥ 8, body weight ≥ 105Kg and distal ATR, received transosseous (TO) distal suture placement (n = 20) rather than the usual transtendinous (TT) technique (n = 55). Patient reported outcome measures and functional evaluation was performed at 12 months following repair., Results: At 12 months follow up both methods resulted in good median (IQR) Achilles tendon Total Rupture Score TO 83.8 (74-88.3) vs. TT 90 (79-94), low increased relative Achilles Tendon Resting Angle TO -3.5˚ (3.6) vs. TT -3.5˚ (3.3) and mean (SD) Single leg Heel-Rise Height Index TO 88.2% (9.9) vs. TT 85.6% (9.9) (n.s.). There were 4 re-ruptures in the high-risk group and 2 in the group receiving TT distal suture placement. All but one of these were traumatic in nature. The mode of failure following TO distal suture placement was proximal suture pull out., Conclusions: To distal suture placement during minimally-invasive Achilles tendon repair for higher-risk patients can lead to results equivalent to those in lower-risk patients treated with a standard TT MIR technique, except for the re-rupture rate which remained higher. There may be factors that have greater influence on outcome other than suture placement following ATR., (© 2024. The Author(s).)

Introduction: Achilles tendon ruptures (ATRs) may occur at varying locations with ruptures at the mid-substance (MS) of the tendon most common, followed tears at the musculotendinous (MT) junction. There is scant literature about the outcome of MT ATR. This study compared the outcome of patients with a MT ATR with patients following a MS ATR., Methods: The diagnostic features and clinical outcome of 37 patients with a MT ATR were compared with a cohort of 19 patients with a MS ATR. Patients in both groups were managed non-operatively and received the same rehabilitation protocol with weight-bearing rehabilitation in protective functional brace., Results: From February 2009 to August 2023, 556 patients presented with an ATR. Of these, 37 (6.7 ​%) patients were diagnosed with a MT tear. At final follow-up, at 12 months following injury, the MT group reported an Achilles tendon total rupture score (ATRS) of mean (standard deviation (SD)) of 83.6 (3.5) (95 ​% confidence interval (CI) 81.8, 85.4) and median (inter-quartile range (IQR)) ATRS of 86 points (78-95.5) and the MS group mean (SD) of 80.3 (8.5) (95%CI) 76.1, 80.5) and median (IQR) of 87 points (59-95) (p ​= ​0.673). Functional evaluation, however, revealed statistically significant differences in mean (SD) heel-rise height index MT group 79 ​% (25) (95%CI 65.9, 92.1) and MS group 59 ​% (13) (95%CI 51.9, 67.1) (p ​= ​0.019). In the MT rupture group, there were considerably less complications than the MS rupture group., Conclusions: When managed non-operatively, with only a 6 weeks period of brace protection, patients have little limitation although have some residual reduction of single heel-rise at the one-year following MT ATR., Level of Evidence: IV., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Introduction: A chronic Achilles tendon rupture (ATR) is defined as an ATR that has been left untreated for more than four weeks following rupture. This systematic review aims to summarize the outcomes of chronic ATR treated using either a gastrocnemius aponeurosis flap or semitendinosus tendon graft., Methods: A systematic search was conducted in three databases (PubMed, Scopus and Cochrane), for studies describing outcomes after surgical treatment of chronic ATR using gastrocnemius aponeurosis flaps or semitendinosus tendon grafts with more than 10 patients included. The studies were assessed for quality and risk of bias using the Methodological Items used to assess risk of bias in Non-Randomized Studies (MINORS)., Results: Out of the 818 studies identified with the initial search, a total of 36 studies with 763 individual patients were included in this systematic review. Gastrocnemius aponeurosis flap was used in 21 and semitendinosus tendon graft was used in 13 of the studies. The mean (SD) postoperative Achilles tendon Total Rupture Score (ATRS) for patients treated with a gastrocnemius aponeurosis flap was 83 (14) points and the mean (SD) American Orthopaedic Foot and Ankle Score (AOFAS) was 96 (1.7) points compared with ATRS 88 (6.9) points and AOFAS 92 (5.6) points for patients treated with a semitendinosus tendon graft. The included studies generally had low-quality according to MINORS, with a median of 8 (range 2-13) for all studies., Conclusion: Both gastrocnemius aponeurosis flaps and semitendinosus tendon grafts give acceptable results with minimal complications and are valid methods for treating chronic ATR. The main difference is more wound healing complications in patients treated with a gastrocnemius aponeurosis flap and more sural nerve injuries in patients treated with a semitendinosus grafts. The current literature on the subject is of mainly low quality and the absence of a patient-related outcome measure validated for chronic ATR makes comparisons between studies difficult., Level of Evidence: Level IV., (© 2023.

Objectives: Management strategies of the COVID pandemic included isolation to prevent transmission. This study aimed to determine if the pandemic of 2020 influenced the epidemiology of Achilles tendon rupture (ATR)., Methods: The demographics of presentations from the local population to Princess Royal Hospital, Shrewsbury & Telford Hospital NHS Trust hospital, Shropshire, United Kingdom, with an ATR were analysed and compared together with the season, month, and year of the injury., Results: From 2009 to 2019, there was no significant change in the incidence of ATR over time with a mean (SD) incidence of 13.3 per 100,000. In 2020, there was a decrease in injuries with an incidence of 8.4 per 100,000, with an increase in 2021 to 22.4 per 100,000. In 2021, there was an increase in injuries from March with numbers maintained until October. The most common activity of ATR was team sport (36.2%), followed by the activities of daily living (28.9%), other physical activities (21.0%), and racket sports (13.9%). In 2020, there was the lowest number of injuries sustained in team and racket sports; however, in 2021, they accounted for over half of injuries., Conclusions: There were significantly more patients sustaining ATR in 2021, the year after the COVID pandemic and mandatory isolation. This was considered to be related to altered activity and team and racket sports during 2020., Levels of Evidence: IV case series., (Copyright © 2022 The Author(s). Published by Elsevier Inc.

Purpose: The aim of this study was to investigate how the Achilles tendon resting angle (ATRA), an indirect measurement of tendon elongation, correlates with ultrasonography (US) measurements of the Achilles tendon length 6 and 12 months after an acute ATR and relates to other clinical outcome measurements such as heel-rise height, jumping ability and patient-reported outcome measurements (PROMs)., Methods: Patients were included following acute Achilles tendon rupture (ATR). Achilles tendon length, ATRA, heel-rise height (HRH), drop countermovement jump (Drop CMJ) and PROMs (Achilles tendon total rupture score (ATRS) and physical activity scale (PAS)) were evaluated 6 and 12 months after injury. Achilles tendon length was evaluated using US, while the ATRA was measured with a goniometer., Results: Sixty patients (13 women, 47 men), mean (SD) age 43 (9) years, with an acute ATR undergoing either surgical (35%) or non-surgical (65%) treatment were evaluated. A negative correlation (r = - 0.356, p = 0.010) between relative ATRA and tendon elongation was seen at 12 months after ATR. There were also significant positive correlations at 6 and 12 months between relative ATRA and HRH (r = 0.330, p = 0.011 and r = 0.379, p = 0.004). There were no correlations between ATRA and ATRS or ATRA and Drop CMJ, at either 6 or 12 months after the injury., Conclusion: In combination with other clinical evaluations such as HRH and US, ATRA could be a clinical tool for indirect measurements of tendon elongation. However, ATRA cannot be recommended as a direct surrogate for US for determining Achilles tendon length., Level of Evidence: III., (© 2022. The Author(s).)

Introduction: The incidence of Achilles tendon ruptures (ATR) has increased over the past few decades. Treatment may be individualised based upon multiple factors including age, pre-injury activity level and the separation of the ruptured tendon ends. Several studies indicate that women may have a poorer self-reported and clinical outcome compared with men, but the number of women in these studies is often small due to the different incidence of ATR between the genders., Aims: The primary aim of this study was to evaluate whether there is a difference in self-reported outcome after an acute ATR between women and men at one to five years following injury. The second aim was to compare the outcome between the surgically and non-surgically treated patients., Methods: Data were obtained from the medical charts of patients treated for an acute ATR between 1 and 2015 and 31 December 2020 at Sahlgrenska University Hospital/Mölndal. The Achilles tendon total rupture score (ATRS) and additional questions relating to treatment and recovery were determined. A multiple regression analysis was performed to isolate the impact of sex when comparing the patient-reported outcome between women and men., Results: A total of 856 patients were included of which 66% participated prospectively. Sex, BMI and age were found to be significant factors influencing the total ATRS score. Female gender resulted in a lower ATRS, 7.8 points (CI = 3.3 to 12.3), than male gender. It was found that treatment did not significantly predict the results of the ATRS., Conclusion: To our knowledge, this is the first report with a larger number of women included showing that female sex predicts inferior self-reported results after an acute ATR., (© 2022.

Purpose: Achilles tendon ruptures are termed chronic after a delay in treatment for more than 4 weeks. The literature advocates surgical treatment with reconstruction to regain ankle push-off strength. The preferred technique is, however, still unknown and is often individualized. This study aims to present the technique and clinical outcome of an endoscopically assisted free semitendinosus reconstruction of chronic Achilles tendon rupture and Achilles tendon re-ruptures with delayed representation. It is hypothesized that the presented technique is a viable and safe alternative for distal Achilles tendon ruptures and ruptures with large tendon gaps., Method: Twenty-two patients (13 males and 9 females) with a median (range) age of 64 (34-73) treated surgically with endoscopically assisted Achilles tendon reconstruction using a semitendinosus autograft were included. The patients were evaluated at 12 months post-operatively for Achilles tendon Total Rupture Score (ATRS), calf circumference, Achilles Tendon Resting Angle (ATRA), heel-rise height and repetitions together with tendon length determined by ultrasonography, concentric heel-rise power and heel-rise work., Results: The patients reported a median (range) ATRS of 76 (45-99) out of 100. The median (range) ATRA on the injured side was 60° (49°-75°) compared with 49.5° (40-61°), p < 0.001, on the non-injured side. Eighteen out of 22 patients were able to perform a single-leg heel-rise on the non-injured side. Sixteen patients out of those 18 (89%) were also able to perform a single heel-rise on the injured side. They did, however, perform significantly lower number of repetitions compared with the non-injured side with a median (range) heel-rise repetitions of 11 (2-22) compared with 26 (2-27), (p < 0.001), and a median (range) heel-rise height of 5.5 cm (1.0-11.0 cm) compared with 9.0 cm (5.0-11.5 cm), (p < 0.001). The median calf circumference was 1.5 cm smaller on the injured side, 37.5 cm compared with 39 cm, when medians were compared. The median (range) tendon length of the injured side was 24.8 cm (20-28.2 cm) compared with 22 cm (18.4-24.2 cm), (p < 0.001), on the non-injured side., Conclusion: The study shows that endoscopically assisted reconstruction using a semitendinosus graft to treat chronic Achilles tendon ruptures and re-ruptures with delayed representation produces a satisfactory outcome. The technique can restore heel-rise height in patients with more distal ruptures or large tendon defects and is therefore a viable technique for Achilles tendon reconstruction., Level of Evidence: IV., (© 2022.

Purpose: Operative repair of Achilles tendon rupture may lead to complications, which influence outcome adversely. The aim of this study was to determine the incidence, impact and response to treatment of post-operative adhesions., Methods: From February 2009 to 2021, 248 patients operated on with percutaneous or minimally invasive surgical repair have been prospectively evaluated using the Achilles tendon Total Rupture Score (ATRS) and Heel-Rise Height Index (HRHI), following acute Achilles tendon rupture., Results: Fourteen (5.6%) patients were identified as having adhesions. Four patients reported superficial adhesions and ten patients reported a deeper tightness of the tendon. At a mean (SD) of 10.5 (2.3) months following repair, the overall ATRS was at a median (IQR) 65 (44.5-78) points and (HRHI) was mean (SD) 81.5 (13.5)%. Of those deemed to have deep adhesions the antero-posterior diameter of the tendon was at mean (SD) 15.6 (4.6) mm. Open release of superficial adhesions resulted in improved ATRS in all patients. Endoscopic debridement anterior to the Achilles tendon led to alleviation of symptoms of tightness and discomfort from deep adhesions and improved outcome in terms of the ATRS score. At a mean (SD) of 15.9 (3.3)-month follow-up from initial rupture and repair, the patients reported at median (IQR) ATRS scores of 85 (64.8-92.8) points, Tegner level 5 (3-9) and mean (SD) HRHI 86.2 (9.5)%. Patients significantly improved both ATRS and HRHI following release at median (IQR) of 16.5 (- 1.8-29.3) points (p = 0.041) and mean (SD) 5.6 (8.3)% (p = 0.043)., Conclusions: The incidence of patient-reported adhesions following minimally invasive repair of Achilles tendon rupture was estimated to be 5.6%. The occurrence of superficial adhesions was associated with a lower outcome scores as well as symptoms of anterior tendon tightness and stiffness were associated with a lower score in most patients. Surgical release of adhesions led to a significant improvement in outcome., (© 2021. The Author(s).)

Background: Achilles' tendon ruptures result in impaired plantar flexion strength and endurance. It is interesting to know the plantar flexion strength, the number of heel-rise repetitions, and the maximal calf circumference following Achilles' tendon ruptures repair., Methods: Both the injured and non-injured legs of thirty male patients with Achilles' tendon ruptures treated with the percutaneous Dresden technique were compared with the ankle function of 30 healthy participants. Rehabilitation involved partial weight-bearing for three weeks and then increased to full weight-bearing and ankle exercises., Results: The injured legs had weaker plantar flexion strength (1.64 ± 0.17 Nm/kg) compared with the non-injured legs (1.91 ± 0.24 Nm/kg; p = 0.002) and the healthy participants' legs (1.93 ± 0.32 Nm/kg; p < 0.001). The non-injured leg had greater ability in doing heel-rise repetitions (39.4 ± 6.1 rep.) compared with the injured legs (37.2 ± 5.7 rep.; p < 0.023) and the healthy participants' legs (31.0 ± 13.0 rep.; p < 0.001)., Conclusions: The injured leg had not recovered full isometric strength but had improved heel-rise repetition., (Copyright © 2021 European Foot and Ankle Society.

Background: During management of Achilles tendon rupture, determination of tendon-end approximation, either clinically or by ultrasound is difficult, following brace application of during loading. The Radiographic Achilles Tendon Loading Angle (RadATLA) is proposed as a method of measuring ankle position whilst loading in a brace during the management of Achilles tendon rupture. This study aims to determine the reliability and reproducibility of the RadATLA., Methods: A loaded true lateral ankle radiograph including the fifth metatarsal head was taken when wearing a brace at the 6-week time point in 18 patients (19 ankles). following Achilles tendon repair or reconstruction. The RadATLA was compared with the Tibio-talar angle, other radiographic and clinical measures used to quantify foot and ankle position during the first 6 weeks of early rehabilitation in a resting position and during loading., Results: The intra-rater reliability of both angles was found to be good (>0.8). The RadATLA was found to have an excellent intra-rater reliability with Intra-class correlation of (ICC) 0.992-0.996 (95%CI 0.889-0.999), standard error of the measurement (SEM) 1.03-3.65 and Minimal Detectable Change (MDC) 2.86-10.12. The inter-rater reliability was good with ICC of 0.798-0.969 (95%CI-0.03 to 0.964), SEM 2.9-7.6, and MDC 8.1-20.9. The RadATLA loaded at 6 weeks in all patients was at mean (SD) (range) 41.9˚ (16.5), (18.5-75.9). There was a significant difference between the patients in the Repair group compared with patients in the Reconstruction group both in RadATLA loaded at 6 weeks: 35.6˚ (11.2), (18.5-56.5) versus 55.5˚ (19), (20-75.9), (p = 0.01). The amount loaded in all patients was at mean (SD) (range) 29.2Kg (17.7), (2-56) and the percentage Body Weight was 30.7% (19), (2.1-63.2). There were no differences between the groups neither in amount loaded nor in percentage Body weight (p = 0.614-0.651)., Conclusions: The RadATLA is a reliable and reproducible angle and can be used to determine the position of the ankle, when loaded in a brace during rehabilitation following Achilles tendon rupture., (Copyright © 2020 European Foot and Ankle Society.

The COVID-19 pandemic has necessitated many novel responses in healthcare including sport and exercise medicine. The cessation of elite sport almost globally has had significant economic implications and resulted in pressure to resume sport in very controlled conditions. This includes protecting pitch-side medical staff and players from infection. The ongoing prevalence of SARS-CoV-2 and the desire to resume professional sport required urgent best practice guidelines to be developed so that sport could be resumed as safely as possible. This set of best practice recommendations assembles early evidence for managing SARS-CoV-2 and integrates expert opinion to provide a uniform and pragmatic approach to enhance on-field and pitch-side safety for the clinician and player. The nature of SARS-CoV-2 transmission creates new hazards during resuscitation and emergency care and procedures. Recommendations for the use and type of personal protective equipment during on-field or pitch-side emergency medical care is provided based on the clinical scenario and projected risk of viral transmission., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Patients often have difficulty recovering knee extension strength post total knee arthroplasty (TKA), and that may reflect alteration of the mechanics including geometry and rollback kinematics, so the purpose of this work was to explore this by comparing the knee extension torque (KET) of the native knee, TKA and patellofemoral arthroplasty (PFA) in response to quadriceps tension. Eight fresh-frozen knees were mounted in a knee extension rig with quadriceps loading and tibial extension torque measurement. Each knee was subject to four conditions: native knee, PFA, cruciate-retaining (CR) and posterior-stabilized (PS) TKA. The KET was measured from 120° to 0° knee flexion. Data were analyzed using one-way ANOVA and post-hoc paired t-tests. The native KET was lowest in terminal extension and 70-100° flexion, and maximal at 20-30° flexion. PFA produced the greatest KET (p < 0.008) compared with native, CR- and PS-TKA, at 30-40° flexion. CR- and PS-TKA had lower KET across 0-50° flexion (p < 0.001 across 0-30°), falling to 25% of the native knee KET or the PFA at full extension. PFA had the highest KET in early flexion possibly due to increased trochlear offset and/or preservation of the cruciate mechanism, so PFA may be more beneficial during the functional range of motion. The claimed benefits of PS- over CR-TKA in deep flexion were not detected. Both CR- and PS-TKAs led to lower KET than the native and PFA knee states across 0-50° flexion. This mechanical effect may help to explain clinical findings of knee extension weakness post-TKA., (Copyright © 2020 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Purpose: This retrospective study aimed to determine the patient-reported and functional outcome of patients with delayed presentation, who had received no treatment until 14 days following injury of Achilles tendon rupture repaired with minimally invasive surgery and were compared with a group of sex- and age-matched patients presenting acutely. Based on the outcomes following delayed presentation reported in the literature, it was hypothesized that outcomes would be inferior for self-reported outcome, tendon elongation, heel-rise performance, ability to return to play, and complication rates than for acutely managed patients., Methods: Repair was performed through an incision large enough to permit mobilisation of the tendon ends, core suture repair consisting of a modified Bunnell suture proximally and a Kessler suture distally and circumferential running suture augmentation., Results: Nine patients presented 21.8 (14.9) days (range 14-42 days) after rupture. The rate of delayed presentation was estimated to be 1 in 10. At 12 months following repair, patients with delayed treatment had median (range) ATRS score of 90 (69-99) compared with 94 (75-100) in patients treated acutely presenting 0.66 (1.7) (0-5) days. There were no significant differences between groups: ATRA [mean (SD) delayed: - 6.9° (5.5), acute: - 6° (4.7)], heel-rise height index [delayed: 79% (20), acute: 74% (14)], or heel-rise repetition index [delayed: 77% (20), acute: 71% (20)]. In the delayed presentation group, two patients had wound infection and one iatrogenic sural nerve injury., Conclusions: Patients presenting more than 2 weeks after Achilles tendon rupture may be successfully treated with minimally invasive repair., Level of Evidence: III.

Background: Achilles tendon rupture leads to weakness of ankle plantarflexion. Treatment of Achilles tendon rupture should aim to restore function while minimizing weakness and complications of management., Purpose: To determine the influence of factors (age, sex, body mass index [BMI], weight, time from injury to operative repair, and tightness of repair) in the initial surgical management of patients after an acute Achilles tendon rupture on 12-month functional outcome assessment after percutaneous and minimally invasive repair., Study Design: Cohort study; Level of evidence, 3., Methods: From May 2012 to January 2018, patients sustaining an Achilles tendon rupture receiving operative repair were prospectively evaluated. Tightness of repair was quantified using the intraoperative Achilles tendon resting angle (ATRA). Heel-rise height index (HRHI) was used as the primary 12-month outcome variable. Secondary outcome measures included Achilles tendon total rupture score (ATRS) and Tegner score. Stepwise multiple regression was used to create a model to predict 12-month HRHI., Results: A total of 122 patients met the inclusion criteria for data analysis (mean ± SD age, 44.1 ± 10.8 years; 78% male; mean ± SD BMI, 28.1 ± 4.3 kg/m 2 ). The elapsed time to surgery was 6.5 ± 4.0 days. At 12-month follow-up, patients had an HRHI of 82% ± 16% and performed 82% ± 17% of repetitions compared with the noninjured side. Participants had a mean ATRS of 87 ± 15 and a median Tegner score of 5 (range, 1-9), with a reduction in Tegner score of 2 from preinjury levels. The relative ATRA at 12 months was -4.8° ± 3.9°. Multiple regression identified younger age (B = ±0.006; P < .001) and greater intraoperative ATRA (B = 0.005; P = .053) as predictors of more symmetrical 12-month HRHI ( R 2 = 0.19; P < .001; n = 120)., Conclusion: Age was found to be the strongest predictor of outcome after Achilles tendon rupture. The most important modifiable risk factor was the tightness of repair. It is recommended that repair be performed as tight as possible to optimize heel-rise height 1 year after Achilles tendon rupture and possibly to reduce tendon elongation., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: Research bursaries were received from the British Association of Sport and Exercise Medicine and the British Orthopaedic Foot and Ankle Society (to M.R.C.).

Purpose: The relationship between the duration of operative time (DOT), healing response and patient outcome has not been previously investigated. An enhanced healing response related to DOT may potentiate repair processes, especially in hypovascular and sparsely metabolized musculoskeletal tissues such as tendons. This study aimed to investigate the association between DOT and the metabolic healing response, patient-reported outcome and the rate of post-operative complications after acute Achilles tendon injury., Methods: Observational cohort, cross-sectional study with observers blinded to patient grouping. A total of two-hundred and fifty-six prospectively randomized patients (210 men, 46 women; mean age 41 years) with an acute total Achilles tendon rupture all operated on with uniform anaesthetic and surgical technique were retrospectively assessed. At 2 weeks post-operatively, six metabolites were quantified using microdialysis. At 3, 6 and 12 months, patient-reported pain, walking ability and physical activity were examined using self-reported questionnaires, Achilles tendon total rupture score, foot and ankle outcome score and physical activity scale. At 12 months, functional outcome was assessed using the heel-rise test. Complications, such as deep venous thrombosis, infections and re-operations, were recorded throughout the study., Results: Patients who underwent longer DOT exhibited higher levels of glutamate (p = 0.026) and glycerol (p = 0.023) at 2 weeks. At the 1-year follow-up, longer DOT was associated with significantly less loss in physical activity (p = 0.003), less pain (p = 0.009), less walking limitations (p = 0.022) and better functional outcome (p = 0.014). DOT did not significantly correlate with the rate of adverse events, such as deep venous thrombosis, infections or re-ruptures. Higher glutamate levels were associated with less loss in physical activity (p = 0.017). All correlations were confirmed by multiple linear regressions taking confounding factors into consideration., Conclusion: The results from this study suggest a previously unknown mechanism, increased metabolic response associated with longer DOT, which may improve patient outcome after Achilles tendon rupture surgery. Allowing for a higher amount of traumatized tissue, as reflected by up-regulation of glycerol in patients with longer DOT, may prove to be an important surgical tip for stimulation of repair of hypometabolic soft tissue injuries, such as Achilles tendon ruptures., Level of Evidence: II.

Background: Following Achilles tendon rupture, tendon elongation leads to long term deficits in calf function. A surrogate measure of Achilles tendon length, Achilles tendon resting angle (ATRA), has been described but has not been validated against length measured using ultrasound. Therefore, the purpose of this study was to validate the ATRA against ultrasound. Secondarily, this study aimed to identify the relationship of other factors (tendon mechanical properties, heel-rise test performance) to the ATRA., Methods: Individuals following unilateral Achilles tendon rupture were included. ATRA was measured in knee flexed and extended positions. Tendon elongation was measured using extended field of view ultrasound imaging. Continuous shear wave elastography quantified tendon mechanical properties. The relationship between variables was tested using Spearman's ρ. Subgroup analysis was used to compare subjects with less then or greater than 1 year following rupture. A total of 42 participants (with a mean of 18.2 months following rupture [SD = 35.9]) were included., Results: Tendon elongation related with relative ATRA with knee flexed (ρ = .491, P = .001) and knee extended (ρ = 0.501, P = .001) positions. In individuals greater than 1 year following rupture, relative ATRA with the knee flexed related to shear modulus (ρ = .800, P = .01) and total work on the heel-rise test (ρ = -.782, P = .008) relative to the uninjured side., Conclusion: Relative ATRA in both knee flexed and knee extended positions has a moderate relationship to tendon elongation within the first year following rupture. After 1 year, the relative ATRA with knee flexed may be a better indicator of tendon elongation and also related to tendon mechanical properties and heel-rise test performance., Level of Evidence: Level III, case-control study.

Purpose: Surgical repair after acute Achilles tendon rupture leads to lower re-rupture rates than non-surgical treatment. After open repair, early functional rehabilitation improves outcome, but there are risks of infection and poor wound healing. Minimal invasive surgery reduces these risks; however, there are concerns about its stability. Consequently, physicians may have reservations about adopting functional rehabilitation. There is still no consensus about the post-operative treatment after minimal invasive repair. The aim of this study was to define the most effective and safe post-operative rehabilitation protocol following minimal invasive repair., Methods: A systematic literature search in Embase, MEDLINE and Cochrane Library for prospective trials reporting on early functional rehabilitation after minimal invasive repair was performed. Seven studies were included., Results: One randomized controlled trail, one prospective comparative and five prospective non-comparative studies were identified. Four studies performed full weight bearing, all demonstrating good functional results, an early return to work/sports and high satisfaction. One study allowed early mobilization leading to excellent subjective and objective results. The only randomized controlled trial performed the most accelerated protocol demonstrating a superior functional outcome and fewer complications after immediate full weight bearing combined with free ankle mobilization. The non-comparative study reported high satisfaction, good functional results and an early return to work/sports following combined treatment., Conclusion: Immediate weight bearing in a functional brace, together with early mobilization, is safe and has superior outcome following minimally invasive repair of Achilles tendon rupture. Our recommended treatment protocol provides quality assurance for the patient and reliability for the attending physician., Level of Evidence: II.

Background: Rupture of the Achilles tendon often leads to long-term morbidity, particularly calf weakness associated with tendon elongation. Operative repair of Achilles tendon ruptures leads to reduced tendon elongation. Tendon lengthening is a key problem in the restoration of function following Achilles tendon rupture. A study was performed to determine differences in initial separation, strength and failure characteristics of differing sutures and numbers of core strands in a percutaneous Achilles tendon repair model in response to initial loading., Methods: Nineteen bovine Achilles tendons were repaired using a percutaneous/minimally invasive technique with a combination of a modified Bunnell suture proximally and a Kessler suture distally, using non-absorbable 4-strand 6-strand repairs and absorbable 8-strand sutures. Specimens were then cyclically loaded using phases of 10 cycles of 100 N, 100 cycles of 100 N, 100 cycles of 190 N consistent with early range of motion training and weight-bearing, before being loaded to failure., Results: Pre-conditioning of 10 cycles of 100 N resulted in separations of 4 mm for 6-strand, 5.9 mm for 4-strand, but 11.5 mm in 8-strand repairs, this comprised 48.5, 68.6 and 72.7% of the separation that occurred after 100 cycles of 100 N. The tendon separation after the third phase of 100 cycles of 190 N was 17.4 mm for 4-strand repairs, 16.6 mm for 6-strand repairs and 26.6 mm for 8-strand repairs. There were significant differences between the groups (p < 0.0001). Four and six strand non-absorbable repairs had significantly less separation than 8-strand absorbable repairs (p = 0.017 and p = 0.04 respectively). The mean (SEM) ultimate tensile strengths were 4-strand 464.8 N (27.4), 6-strand 543.5 N (49.6) and 8-strand 422.1 N (80.5). Regression analysis reveals no significant difference between the overall strength of the 3 repair models (p = 0.32) (4 vs. 6: p = 0.30, 4 vs. 8: p = 0.87; 6 vs. 8: p = 0.39). The most common mode of failure was pull out of the Kessler suture from the distal stump in 41.7% of specimens., Conclusion: The use of a non-absorbable suture resulted in less end-to-end separation when compared to absorbable sutures when an Achilles tendon repair model was subject to cyclical loading. Ultimate failure occurred more commonly at the distal Kessler suture end although this occurred with separations in excess of clinical failure. The effect of early movement and loading on the Achilles tendon is not fully understood and requires more research.

Background: The aim of management of Achilles tendon rupture is to reduce tendon lengthening and maximize function while reducing the rerupture rate and minimizing other complications., Purpose: To determine changes in Achilles tendon resting angle (ATRA), heel-rise height, patient-reported outcomes, return to play, and occurrence of complications after minimally invasive repair of Achilles tendon ruptures using nonabsorbable sutures., Study Design: Cohort study; Level of evidence, 3., Methods: Between March 2013 and August 2015, a total of 70 patients (58 males, 12 females) with a mean age of 42 ± 8 years were included and evaluated at 6 weeks and 3, 6, 9, and 12 months after repair of an Achilles tendon rupture. Surgical repair was performed using either 4-strand or 6-strand nonabsorbable sutures. After surgery, patients were mobilized, fully weightbearing using a functional brace. Early active movement was permitted starting at 2 weeks., Results: There were no significant differences in the ATRA, Achilles Tendon Total Rupture Score (ATRS), and Heel-Rise Height Index (HRHI) between the 4- and 6-strand repairs. The mean (SD) relative ATRA was -13.1° (6.6°) (dorsiflexion) following injury; this was reduced to 7.6° (4.8°) (plantar flexion) directly after surgery. During initial rehabilitation at 6 weeks, the relative ATRA was 0.6° (7.4°) (neutral) and -7.0° (5.3°) (dorsiflexion) at 3 months, after which ATRA improved significantly with time to 12 months ( P = .005). At 12 months, the median ATRS was 93 (range, 35-100), and the mean (SD) HRHI and Heel-Rise Repetition Index were 81% (0.22%) and 82.9% (0.17%), respectively. The relative ATRA at 3 and 12 months correlated with HRHI ( r = 0.617, P < .001 and r = 0.535, P < .001, respectively)., Conclusion: Increasing the number of suture strands from 4 to 6 does not alter the ATRA or HRHI after minimally invasive Achilles tendon repair. The use of a nonabsorbable suture during minimally invasive repair when used together with accelerated rehabilitation did not prevent the development of an increased relative ATRA. The ATRA at 3 months after surgery correlated with heel-rise height at 12 months., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: Funding for this study was provided in part by the British Association of Sport and Exercise Medicine (to M.R.C.).

Aim: This systematic review and meta-analysis sought to identify return to play (RTP) rates following Achilles tendon rupture and evaluate what measures are used to determine RTP., Design: A systematic review and meta-analysis were performed. Studies were assessed for risk of bias and grouped based on repeatability of their measure of RTP determination., Data Sources: PubMed, CINAHL, Web of Science and Scopus databases were searched to identify potentially relevant articles., Eligibility Criteria for Selecting Studies: Studies reporting RTP/sport/sport activity in acute, closed Achilles tendon rupture were included., Results: 108 studies encompassing 6506 patients were included for review. 85 studies included a measure for determining RTP. The rate of RTP in all studies was 80% (95% CI 75% to 85%). Studies with measures describing determination of RTP reported lower rates than studies without metrics described, with rates being significantly different between groups (p<0.001)., Conclusions: 80 per cent of patients returned to play following Achilles tendon rupture; however, the RTP rates are dependent on the quality of the method used to measure RTP. To further understand RTP after Achilles tendon rupture, a standardised, reliable and valid method is required., Competing Interests: Competing interests: None declared., (Published by the BMJ Publishing Group Limited.

Purpose: Syndesmotic sprains are uncommon injuries that require prolonged recovery. The influence of ultrasound-guided injections of platelet-rich plasma (PRP) into the injured antero-inferior tibio-fibular ligaments (AITFL) in athletes on return to play (RTP) and dynamic stability was studied., Methods: Sixteen elite athletes with AITFL tears were randomized to a treatment group receiving injections of PRP or to a control group. All patients followed an identical rehabilitation protocol and RTP criteria. Patients were prospectively evaluated for clinical ability to return to full activity and residual pain. Dynamic ultrasound examinations were performed at initial examination and at 6 weeks post-injury to demonstrate re-stabilization of the syndesmosis joint and correlation with subjective outcome., Results: All patients presented with a tear to the AITFL with dynamic syndesmosis instability in dorsiflexion-external rotation, and larger neutral tibia-fibula distance on ultrasound. Early diagnosis and treatment lead to shorter RTP, with 40.8 (±8.9) and 59.6 (±12.0) days for the PRP and control groups, respectively (p = 0.006). Significantly less residual pain upon return to activity was found in the PRP group; five patients (62.5 %) in the control group returned to play with minor discomfort versus one patient in the treatment group (12.5 %). One patient in the control group had continuous pain and disability and subsequently underwent syndesmosis reconstruction., Conclusions: Athletes suffering from high ankle sprains benefit from ultrasound-guided PRP injections with a shorter RTP, re-stabilization of the syndesmosis joint and less long-term residual pain., Level of Evidence: II.

Background: Rupture of the Achilles tendon may result in reduced functional activity and reduced plantar flexion strength. These changes may arise from elongation of the Achilles tendon. An observational study was performed to quantify the Achilles tendon resting angle (ATRA) in patients following Achilles tendon rupture, surgical repair, and rehabilitation, respectively., Methods: Between May 2012 and January 2013, 26 consecutive patients (17 men), with a mean (standard deviation, SD) age of 42 (8) years were included and evaluated following injury, repair, and at 6 weeks, 3 months, 6 months, 9 months, and 12 months, respectively (rehabilitation period). The outcome was measured using the ATRA, Achilles tendon total rupture score (ATRS), and heel-rise test., Results: Following rupture, the mean (SD) absolute ATRA was 55 (8)° for the injured side compared with 43 (7)° ( p  < 0.001) for the noninjured side. Immediately after repair, the angle reduced to 37 (9)° ( p  < 0.001). The difference between the injured and noninjured sides, the relative ATRA, was -12.5 (4.3)° following injury; this was reduced to 7 (7.9)° following surgery ( p  < 0.001). During initial rehabilitation, at the 6-week time point, the relative ATRA was 2.6 (6.2)° ( p   =  0.04) and at 3 months it was -6.5 (6.5)° ( p  < 0.001). After the 3-month time point, there were no significant changes in the resting angle. The ATRS improved significantly ( p  < 0.001) during each period up to 9 months following surgery, where a score of 85 (10)° was reported. The heel-rise limb symmetry index was 66 (22)% at 9 months and 82 (14)% at 12 months. At 3 months and 6 months, the absolute ATRA correlated with the ATRS ( r  = 0.63, p   =  0.001, N   =  26 and r  = 0.46, p   =  0.027, N   =  23, respectively). At 12 months, the absolute ATRA correlated with the heel-rise height ( r  = -0.63, p   =  0.002, N   =  22)., Conclusion: The ATRA increases following injury, is reduced by surgery, and then increases again during initial rehabilitation. The angle also correlates with patient-reported symptoms early in the rehabilitation phase and with heel-rise height after 1 year. The ATRA might be considered a simple and effective means to evaluate Achilles tendon function 1 year after the rupture.

Sural nerve injury is a relatively common complication after surgery on the Achilles tendon. Studies to determine the course of the sural nerve have been performed on cadaveric specimens. The purpose of this cross-sectional study was to use ultrasound to determine the relations of the sural nerve in a healthy population. The authors performed ultrasound examination of the posterior triangle of the ankle and Achilles tendon to determine the course of the sural nerve relative to the Achilles tendon in healthy participants. The mean distance between the nerve and the tendon was 21.48, 11.47, 5.8, and 0.81 mm lateral to the Achilles tendon as measured at the insertion and 4, 8, and 11 cm proximally, respectively. Male participants tended to have a nerve that was initially more lateral to the Achilles insertion compared with women. The distance between the sural nerve and the Achilles tendon was found to be lower in older participants, with the nerve passing significantly closer to the tendon at all levels (P<.01). Three anatomical variants were reported, with the nerve crossing the lateral border of the Achilles low or high or with multiple branches yet to converge. The course of the sural nerve can be visualized and plotted relative to the Achilles tendon using ultrasound examination in healthy participants. Older patients may be at an increased risk of iatrogenic nerve injury because the nerve courses closer to the Achilles tendon than that in young patients. Intraoperative ultrasound examination may be a useful modality to prevent sural nerve injury during Achilles tendon surgery., (Copyright 2014, SLACK Incorporated.)

In recognition of Open Access week (21st-27th October 2013), we asked some BMC Medicine Editorial Board Members to share their views and experiences on open access publishing. In this short video, they highlight the benefits of visibility and dissemination of their research, and discuss the future directions for this model of publishing.

Background: The resting angle of the ankle joint may be altered following apparently successful management of Achilles tendon rupture. The reliability of the Achilles Tendon Resting Angle and Calf Circumference measurements was determined., Methods: Three test-retest measurements for reliability assessment were performed on 16 healthy subjects: 10 males and 6 females., Results: The mean left Achilles Tendon Resting Angle was mean 50.1° (range [26-61]), ICC 0.92 (CI [0.83-0.97]), SEM 2.4°. The mean right Achilles tendon resting angle was mean 49.9° (range [26-60]), ICC 0.91 (CI [0.80-0.96]), SEM 2.6°. The mean left calf circumference was mean 38.5cm (range [33.3-44.2]), ICC 0.97 (CI [0.94-0.98]), SEM 0.6cm, and the mean right calf circumference was mean 38.4cm (range [33.3-43.6]), ICC 0.97 (CI [0.94-0.99]), SEM 0.5cm., Conclusions: The Achilles Tendon Resting Angle and Calf Circumference at 15cm from the antero-medial joint line had excellent test-retest reliability. These are simple, quick and inexpensive measurements, which have the potential to correlate with tendon elongation and functional outcome. The Achilles tendon resting angle may be used as a guide to tendon length during intra-operative repair and rehabilitation., (Copyright © 2013 European Foot and Ankle Society.

Chronic, exercise-related groin pain is a debilitating condition. Nonoperative treatment has limited efficacy, but surgical intervention on the adductor-abdomino complex may be used to alleviate symptoms and allow return to play (RTP). The purpose of this study was to report the outcome of adductor tenotomy and hernioplasty for professional soccer players with groin pain. Between 2000 and 2006, a total of 155 professional and recreational soccer players with recalcitrant groin pain (with or without lower abdominal pain) and resistance to conservative treatment were included in this retrospective analysis. Ninety-six patients were treated with adductor tenotomy and 59 patients were treated with combined adductor tenotomy and hernioplasty. No difference in pre- or postoperative parameters was detected between groups, apart from abdominal wall muscle defects revealed during ultrasound for patients in the combined group. The RTP time and subjective and objective outcome measures were compared. A combined score was developed to evaluate outcomes that consisted of overall satisfaction (50%), RTP time (15%), and Tegner scores (35%). Mean RTP was 11 weeks (range, 4-36 weeks). Postoperative Tegner score remained 8.2 (same as the preinjury Tegner score). Subjective outcome was rated 4.3 of 5. The combined score indicated 80% of good or excellent results for both groups. Surgical intervention allows RTP at the same level in professional soccer players following failure of nonoperative treatments. Athletes with adductor syndrome and accompanying sportsman's hernia may benefit from adductor tenotomy alone., (Copyright 2013, SLACK Incorporated.)

Background: Randomized studies have so far failed to show a difference in outcome between operative and nonoperative management of Achilles tendon rupture, provided that no rerupture occurs. Percutaneous Achilles repair has been suggested to result in superior patient satisfaction compared with open repair in patients with an acute Achilles tendon rupture, but there are no outcome data available with validated methods describing the progression of recovery during the first year., Purpose: To evaluate the outcome of patients with a ruptured Achilles tendon, managed by percutaneous repair, during the first year following repair with a valid, reliable, and responsive outcome measure. Furthermore, the effects of time between injury and surgery, age, and complications on outcome were also evaluated., Study Design: Case series., Methods: A total of 73 patients (60 males and 13 females) with a mean age of 45.5 years were included. Patient age, length of time between injury and surgery, and complications were documented. Patients were evaluated using the Achilles tendon Total Rupture Score (ATRS) at 3, 6, 9, and 12 months following repair., Results: The median ATRS results at 3, 6, 9, and 12 months were 42.5, 73, 83, and 89, respectively. The number of patients who reported excellent or good scores (ATRS >84) at 3, 6, 9, and 12 months were 3%, 36%, 57%, and 69%, respectively. There were no significant differences in outcome at each time point for those patients undergoing early (≤48 hours) compared with late surgery or between those <65 and those >65 years of age. The complication rate was 13.5%. Patients who had a complication had a lower ATRS result at 3 months following surgery, but there were no differences after that time point., Conclusion: The patients in the present study reported marked improvement in function between 3 and 6 months following surgery, with continuing but less steep improvement up to 1 year following surgery. The presence of a complication other than rerupture did not affect the end-stage outcome but did affect that at 3 months following surgery., Clinical Relevance: This study demonstrates improving scores with time over the first year following surgery, against which other treatment methods can be compared.

Purpose: The Achilles tendon Total Rupture Score (ATRS) was developed because of the need for a reliable, valid and sensitive instrument to evaluate symptoms and their effects on physical activity in patients following either conservative or surgical management of an Achilles tendon rupture. Prior to using the score in larger randomized trial in an English-speaking population, we decided to perform reliability, validity and responsiveness evaluations of the English version of the ATRS. Even though the score was published in English, the actual English version has not be validated and compared to the results of the Swedish version., Methods: From 2009 to 2010, all patients who received treatment for Achilles tendon rupture were followed up using the English version of the ATRS. Patients were asked to complete the score at 3, 6 and 12 months following treatment for Achilles tendon rupture. The ATRS was completed on arrival in the outpatient clinic and again following consultation., Results: The outcomes of 49 (13 female and 36 male) patients were assessed. The mean (SD) age was 49 (12) years, and 27 patients had treatment for a left-sided rupture, 22 the right. All patients received treatment for ruptured Achilles tendons: 38 acute percutaneous repair, 1 open repair, 5 an Achilles tendon reconstruction using a Peroneus Brevis tendon transfer for delayed presentation, 1 gracilis augmented repair for re-rupture and 4 non-operative treatment for mid-portion rupture. The English version of ATRS was shown to have overall excellent reliability (ICC = 0.986). There was no significant difference between the results with the English version and the Swedish version when compared at the 6-month- or 12-month (n.s.) follow-up appointments. The effect size was 0.93. The minimal detectable change was 6.75 points., Conclusions: The ATRS was culturally adapted to English and shown to be a reliable, valid and responsive method of testing functional outcome following an Achilles tendon rupture.

Purpose: Recent meta-analyses have shown reduced re-rupture rates for the surgical management of Achilles ruptures. However, percutaneous repair has been demonstrated to lead to improved function and patient satisfaction but greater complications than open repair. In the current economic climate, it is reasonable to consider the financial cost of rupture management for both the patient and the provider. The cost-effectiveness of operative treatment of ruptures of the Achilles tendon was determined based upon theatre occupancy, clinic attendance and cast changes, operative complications and functional assessment score., Methods: The cost-effectiveness of the surgical management of Achilles tendon ruptures between 2005 and 2011 in our unit was audited by comparing 49 patients receiving percutaneous repair to 35 patients whom had open repairs., Results: There was no significant difference in complications between the two surgical techniques: (Open vs. Percutaneous) overall rates 14.3 versus 10.4 %: infection; 2.7 versus 2.0 %, transient sural nerve damage: 5.6 versus 8.1 %, wound breakdown: 2.8 versus 0.0 %, re-rupture: 2.8 versus 2.0 %. Achilles Total Rupture Scores (ATRS) were comparable [Open 89 (65-100) at 49 months vs. Percutaneous 88.8 (33-100) at 12 months (n.s.)]. Theatre occupancy (P < 0.00) and hospital stay (P < 0.00) were significantly longer with open repair [43 min (26-70) and 2.9 days (0-4)] compared to percutaneous repair [15 min (12-43) and 1.2 days (0-2)]. Excluding the costs of running the operating theatre, we have estimated the costs of surgery for open repair to be £ 935 and percutaneous repair to be £ 574., Conclusions: This study suggests that percutaneous repair of the Achilles tendon resulted in reduced costs and yet had comparable outcome and complications rates to open repair in surgical management of the Achilles tendon. Percutaneous repair should be considered as the primary method of cost-effective surgical management of Achilles tendon rupture.

Cycling has been shown to confer considerable benefits in terms of health, leading to reductions in death rates principally due to cardiovascular improvements and adaptation. Given the disparity between the benefits of cycling on cardiovascular fitness and previous research finding that cycling may not be beneficial for bone health, Hugo Olmedillas and colleagues performed a systematic review of the literature. They concluded that road cycling does not appear to confer any significant osteogenic benefit. They postulate that the cause of this is that, particularly at a competitive level, riders spend long periods of time in a weight-supported position on the bike. Training programs may be supplemented with impact loading to preserve bone health; however, the small increased risk of soft tissue injury must also be considered.

Introduction: Meniscal scaffold implants support the in-growth of new "meniscus like" tissue with the aim of alleviating post-meniscectomy knee pain and preventing further articular cartilage degeneration., Patients and Methods: Twenty-three patients underwent meniscal scaffold implantation (14 medial, 9 lateral) with either the Menaflex (ReGen Biologics) (n=12) or Actifit (Orteq) (n=11) scaffolds. Minimum follow-up was 1 year with a mean of 24.1 months (18-27) for the Menaflex and 14.7 months (12-18) for the Actifit groups. Mean age at surgery was 35 years (17-47) with a mean Outerbridge grade of 1.9 in the affected compartment. Eight (36%) underwent concurrent osteotomy, ligament reconstruction or microfracture of the tibial plateau. KOOS, Lysholm, Tegner activity and IKDC scores were collected pre-operatively and at six-month interval post-surgery. Assessment of the reconstruction was obtained with MRI scanning and arthroscopy. One scaffold tore and was revised at 19 months post-operatively., Results: Twenty-one out of 23 (91.3%) had a significant improvement in knee scores when compared to pre-surgery levels at latest follow-up. Second-look arthroscopy in 14 at 1-year post-implantation showed variable amounts of regenerative tissue. There was no progression in chondral wear noted on repeat MRI scanning., Conclusion: Treatment with meniscal scaffold implants can provide good pain relief for the post-meniscectomy knee following partial meniscectomy. Longer follow-up is required to ascertain whether they also prevent the progressive chondral wear associated with a post-meniscectomy knee., (Copyright © 2012 Elsevier B.V. All rights reserved.)

Background: The stump impingement reflex is a subtle bounce to the knee thought to be caused by hamstring contraction when the knee is brought into extension and the torn ACL stump impinges between the distal femur and the tibial plateau. We have studied the diagnostic value of this sign., Findings: From Feb 2008-Feb 2009, we audited 30 patients who underwent urgent arthroscopy for acutely locked knees. The presence of the stump impingement reflex prior to surgery was compared with the intra-operative findings. The diagnostic values of the stump impingement sign were found to be: Sensitivity 58%, Specificity 81%, Positive predictive value 70%, Negative predictive value 72% and Accuracy 71%., Conclusions: We believe that the stump impingement reflex is a specific sign for ACL stump impingement as a cause of knee locking. We recommend close inspection for this sign when examining locked knees.

Introduction: The Accessory Postero-Lateral (AccPL) portal has recently been described to improve the visualisation for the endoscopic debridement of Haglund's tubercle. The safety of using this portal has been considered previously for posterior ankle arthroscopy. We performed a study to determine the proximity of the AccPL portal to the sural nerve., Methods: We compared the distances between AccPL and PL portals to the sural nerve in 17 cadaveric specimens., Results: The AccPL portal was significantly closer (mean 12.0mm, range 6-19 mm, SD=3.64) to the sural nerve than the PL portal (mean 14.1mm, range 11-18 mm, SD=2.34) (t(16)=-2.34, p=0.03). In two cases the sural nerve was in contact with the clip but on close inspection, the nerve had not been damaged in any of the specimens., Conclusions: We conclude that the AccPL portal is a safe method to allow visualisation during endoscopic debridement of the Achilles tendon insertion. We also recommend that the portal is used for visualisation rather than instrumentation., (Copyright © 2011 European Foot and Ankle Society. Published by Elsevier Ltd. All rights reserved.)
